multitenant-down

Tear down the multi-tenant K8s stack:

1. Kill all port-forwards:

   pkill -f 'port-forward.*duckgres' 2>/dev/null
   

2. Delete the duckgres namespace (removes control plane, workers, RBAC, services):

   kubectl delete namespace duckgres --ignore-not-found
   

3. Stop the config store:

   docker compose -f k8s/local-config-store.compose.yaml down
